Hi, can the xert EBC already be run on the new Hammerhead Karoo 3?

From what I understand, itâs not supported directly on the device like with K1/K2. It may be possible to side-load the app, but itâs not something we have tried/tested.
Iâm thinking to buy the new Karoo.
Does anyone have one and is willing to share some feedback?
As of June 3rd, 2024, it is not possible to install Xert on the Hammerhead Karoo 3 through the native Hammerhead Karoo App store. However, you might be able to sideload it using instructions from sources like DC Rainmaker and the APK from a site like APKPure.
From what I understand, Hammerhead has not yet released the SDK for the Hammerhead Karoo 3. This SDK is necessary to create data fields such as the XSS and MPA fields available with the Xert app on the Hammerhead Karoo 2. Although people expect the SDK to be updated or released soon, there is no official communication about it as far as I know.

Cheers for the update.
I have a thought decision to make⊠I have been waiting for the K3 for quite a while. My current bike computer is my old Samsung Galaxy S7. The phone is already owning some time to the grave.
I donât want to buy Garmin. Wahoo doesnât appeal to me.
If i buy the K3 I run the risk of not having a compatible device with my training platform.
Having to have a bike computer plus a phone to run EBC is s.
Would it be possible to add datafields like with the Garmin? Iâm thinking specifically of things like the MPA/Power and XSS Buckets datafields.
You need to side load Xert into K3 (not tested) and switch between apps during the ride.
Like explained above, hammerhead didnât realised the sdk package yet. Xert have no way to create does fields inside the HH app.
Are there any plans to update the Xert app for the K3 if the SDK gets released?
I would imagine they would specifically release the SDK to get support for our app.
Just as a data point: Iâve been using Xert EBC on the Karoo 3 for indoor training. It installs fine via adb. Until SRAM unlocks the SDK, no datafields can be developed (no Ki2, no Xert, etc.). So you wonât be able to use Xert during a ride for now, unless you want to track via EBC.

Hi, what is the current status of Xert app and Xert datafields on karoo 3? It is possible to load datafieds somehow? Iâm mainly interested in the fields when I run outside.
EDIT:
I just ask Hammerhead about that, there is the âfreshâ statment:
Thank you for your question about the SDK for the Karoo.
We are yet to implement SDK capability on the Karoo. It is an ongoing project our product team is working on for the near future release, I do not have the timeline yet but we will release an SDK for the Karoo.
I know that several community members are waiting for the SDK! We appreciate your patience and interest in the new Karoo.

Thanks for the update @ketyas! We havenât heard anything from them yet. Iâm sure theyâll make a formal announcement when everything is ready.
And here it is now: GitHub - hammerheadnav/karoo-ext: Android library for Karoo System extensions and interactions

@ManofSteele assuming this works as expected, will the Xert data fields be ported over to the Karoo 3? I might get tempted by a Karoo 3 if thereâs a decent Black Friday sale. 
Is that is the official SDK for a Karoo 3?
Hard to tell since Hammerhead doesnât distinguish between the original Karoo (which I assume is defunct) and the current model also known as Karoo, not to be confused with a Karoo 2. 
Itâs on official hammerhead GitHub account, and they are saying that it should replace old SDK for new and old devices, so I assume. Yes it is for Karoo 3 also.
Really looking forward to this coming to KAROO (3) SDK. I would also love to see Daily Workout âExportâ button (Paper aeroplane 
), listing HH KAROO. Especially as Wahoo, Garmin, Zwift, are all there already.

OK so I got a Karoo 3. The way any 3rd party android app can now get loaded via the Karooâs companion app is awesome.
Hopefully Xertâs ConnectIQ data fields can get ported over soon! Paging @dbrillha
BTW here are some very early Karoo-specific apps:
